How it applies
Common Examples

Lighting Rig Injury at Concert
Southern Studios purchased a lighting rig from Brook Media and delivered it to Ridge Stage for a concert. Ridge Stage employees installed the rig with minor adaptations for the venue grid. Trent, who bought only a ticket, stood in the audience when the rig fell and caused his injuries. Trent qualifies as the end user whose harm triggers the manufacturer's strict liability exposure.
Telecom Network Sharing Dispute
An ILEC refused to share network elements with a CLEC that wanted to resell local service to residential customers. The CLEC planned to purchase services at wholesale rates specifically for resale to end users in the local market. The distinction between wholesale and retail traffic turned on whether the ultimate purchasers were end users rather than the CLEC itself.

Defective Wheel on Family Car
Buick sold an automobile to a dealer who resold it to the buyer. The buyer lent the car to a friend who was injured when a defective wheel collapsed during ordinary driving. The friend, as the person actually operating the vehicle for its intended purpose, stood in the position of end user whose injury the manufacturer could not escape by claiming lack of privity.

Operating System Licensing Limits
Microsoft required OEMs to install its operating system on every computer they shipped. End users who purchased those machines received the software pre-installed and could not readily obtain competing browsers. The restriction affected the choices available to the end users who ultimately ran the software on their own devices.

Shrinkwrap License Enforcement
ProCD sold a database on CD-ROM accompanied by a license inside the box. Zeidenberg purchased the product and loaded it onto his computer for his own research. As the end user who actually operated the software, Zeidenberg became bound by the license terms that appeared when he first ran the program.

Power Tool Vibration Claim
Chicago Pneumatic sold grinders to distributors who resold them to construction companies. Workers at those companies used the tools daily and later developed hand-arm vibration syndrome. The workers, as the end users who operated the tools in their intended manner, could recover under strict liability even though they had not purchased the grinders directly from the manufacturer.

Common questions
Frequently Asked
4
Does the term end user include automated scripts that access software?+
No. Courts interpreting license agreements give the term its generally prevailing meaning, which refers to human operators rather than background processes. When a contract uses users without a special definition, automated scripts are treated as tools rather than end users.
Supporting sources
Why does strict products liability extend to end users who lack privity with the manufacturer?+
The rule protects the ultimate consumer or user who encounters the product in the stream of commerce. Liability attaches even without a direct sale because the product is expected to reach that party without substantial change.
Supporting sources
How does the end user concept affect interpretation of software license fees?+
When fees are calculated per user, the term is read according to ordinary meaning unless the contract shows otherwise. Human employees who log in count as end users. Automated processes that merely touch the system do not.
Supporting sources
Can an intermediate distributor qualify as an end user?+
No. The designation applies only to the party for whom the product is ultimately designed and who employs it for its intended purpose. Distributors and resellers occupy an earlier position in the chain and are not end users.
